Callback for materializecss dialog

Hello everyone,

I’m pretty new to web development, so hopefully you can give me a hint.
I’m using the modal function from the materializecss framework on every post. That is working great until the first infinite scroll is called. After that the dialogs won’t open. If I change to pagination or “load more” all dialogs are working. So, I think I need to callback the modal function…but I don’t know how. The modal function needs to be initialized through

$(document).ready(function(){
    // the "href" attribute of .modal-trigger must specify the modal ID that wants to be triggered
    $('.modal').modal();
  });

The link to the modal function:

Best regards,
Vik
